T aZZio/mmit may concern:

Be it known thatI, PAULIF. SoHENo'r,

a citizen of the Unitedstates, and resident Castle Shannon, in the county of Allegheny and State otPennsylvania, have invented a new and useful Improvement in My invention relates to apparatus for suppl *inglubricatmg oil to automobileengines,

and is particularly designed for theengines ofF-ord automobiles,although my invention-may also beemployed with advantage on other types of automobile engines, partem of lubrication. 7

One object of myinvention is to provide an improved device for supplying 'oil to an automobile engine, whereby the oil may be introduced while the engine is running and in a'convenicnt manner. 7

Another object of my invention is to provide an oil-filling device which shall also include an indicator for showing the quantity of oil in the crank case of the engine.

A further object of my invention is to provide an oil-filling device for automobile engines which shall include asupply tank, and which shall thereby increase the length of time that the engine will run properly without replenishing the oil.

It is a matter of some inconvenience to pour motor oil into the crank case of a Ford engine. and when the driver oesires to know how much oil remains in the crank case it is necessary to open one or more of the petrocks which 18 still more inconvenient.

According to my present invention I avold both of these inconveniences by providing an oilsupply tank connected by means of a suitable pipe to one of the pet-cocks of the crank case. and also connected'by means of a vertical pipe to a filling pipe or funnel located upon "the floor of the car near the seat. Oil may be conveniently poured through the filler pipe at anytime, whether the engine is running or not. The vertical pipe through which oil is poured into the supply, tank is also employed as a gauge to indicate the quantity of oil in the system. For this purpose a rod extends through the vertical pipe and is provided with a float which causes the upper end of the rod to protrude from the filling pipe to an amount corresponding to the level of Fig.4 is an inverted ply tank cap. ticularly those employing the splash syscocks 3 and 4 and the drain cock 5.

oil in the supply tank.'- Since the oil in the supply tank isalways'at the same level as the oil in the crankcase,- the indicator rod shows at all times the levelof oil in' the crank case; i

The pipe 9 may suitably consist of -inch copper tubing.

.The supply tank 10 is provided with an internally threaded ,seat 11 in which is screwed a cap 12' provided with a screw threaded opening 13 which receives the screw-threaded end ofv a vertical pipe 14. The cap 12 is employed in order to give access to the interior of the tank 10 for cleaning or adjustment. Thecap 12 may, for

' example, be 1- inches indiameter, and the vertical pipe 14 may be 14 inchin diameter. The tank 10 may be about 9 inches. long,' l inches deep and 3 inches wide, in which case it holds approximately 1 quart of oil. My invention is of course not limited tothese dimensions,- which are stated for illustration only.

The upper end of the-vertical pipe 11 extends through an opening 15in one of the 'tl'oorboards, this opening-being as near to "the SeatS- as is convenient. The upper end of the pipe 14 is screw-threaded, as shown at 16 "for attachment to an internally threaded flange 17 which is attached to the floor board 6 by means of screws 18 or otherwise and carries a filler pipe 19. This filler pipe may suitably consist of a short length OI" 1% n h p p the lower end of which is 24 are provided for the rod 21 and,-as-

shown, each of these guides consists of a short strip of metal extending d1ametr1cally across the upper and lower ends of the pipe 14 and each having an opening 24 through which the rod 21. slides loosely. The guide strips 23 and 24 may suitably be secured to the upper and lower surfaces, respectively, of the flange 17 and the tank cap 12. -V

The rod 21 is of such length that when the tank 10 is filled with oil the rod protrudes above the cap 20 a distance substantially equal to the depth of the tank 10, so thatwhen the upper end of the rod 21 sinks to the level of the cap 20 this indicates that the tank 10 is empty. The upper end ofthe rod 21 may, if desired, be provided with graduations, as shown at 25, to indicate the quantity of oil in the tank 10, and a projec tion 26 may be formed at the top of the rod 21 to prevent the upper end of the rod from being forced below the cap 20.

The upper surface of the tank 10 is preferably at, or slightly above, the level of the upper petcock 3, so that when the tank 10 is completely filled with oil the oil in the crank case standsat the level of this petcock; Oil may be introduced into the engine at any time by merely removing the cap 20 and pouring the oil into the upper end of the filler pipe 19. On account of the reserve supply of oil provided in the oil tank 10,

7 this addition of oil need only be made at comparatively long intervals. indicates at all times the level ofthe oil in the system, and this level may be ascertained at anytime, either by looking at the device,-

or by touch.

I claim as my invention: 1 l. Lubricating apparatus for automobile engines comprising an oil-supply tank, means for connecting said tank-to the crank case of: the automobile engine, a vertical pipe for introducing oil into the said tank,

the upperend of the said vertical pipe be- 7 I place by any other de- The rod 21 ing disposedadjacent to the drivers seat, a filler pipe of larger diameter. than the said vertical pipe and secured to the upper end of said vertical pipe, and a cap for closing the upper end of said filler pipe.

2. Lubricating apparatus for automobile engines comprising an oil supply tank, a pipe connecting said supply tank to the crank case of the automobile engine, a verti- V I cal pipe for introducing oil into said tank,
